2. Would you rather have one strongman or many weak men?
Would you believe that even very strong muscles are made up of molecules that are largely held together by many weak interactions?

3. Interactions are important…
Atoms in water are held together by strong bonds: Shake the water molecule. Does it come apart?
Water molecules in a glass are held together by weak bonds: Shake 2 water molecules. Do they come apart?
Compare interactions between water, alcohol and ethane.

4. Actually a combination of weak and strong interactions are important…
Explore the molecules of life…
Where can you find strong interactions?
Where can you find weak interactions?

5. Weak interactions help provide shape that is critical for molecules to work right…
Fold the toober using the rules designated.
This is how proteins fold, like the muscle protein myosin.
Weak interactions between amino acids hold them in the correct shape.
The many interactions between the amino acids of a protein allow each protein to fold in a way that they can do a different job
